and useful Improvements in Universal Joints; and I do declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use th same.

This invention relates to improvements in universal joints and. has for .its object the production of a device of the kind that is simple and durable in construction and positive in action.

With this and other objects in view the invention consist-s in the construction and combination of parts to be hereinafter described in the following specification and pointed out in the claim and illustrated in the accompanying drawings which form a part of said specification.

In the drawings: Figure 1 is a plan view" of my invention complete. Fig. 2 is a vertical cross sect-ion in elevation taken on line 22. Fig. 3 is a section on line 3-3 of Fig. 2.

Like reference characters indicate corresponding parts throughout the several views.

y shaft-like members 2 and 3 having their relatively remote extremities squared internally as at 4 to receive the ends ofshafts to be coupled; the engaged extremities of said members 2 and 3 are respectively shell-like and solid, the former surrounding the latter, and the shell-like extremity of shaft-like member 2 being formed with two diametri-' cally opposed longitudinal slots 5 through which extend prongs 6 of member 3, made integral therewith, and secured against lateral oscillation within longitudinal slots 5 by a suitable sliding block 7 and screw 8 engaging ari internal thread of prong 6. The

invention comprises preferably two.

intermediate portion of member 2 is provided with an internal longitudinal opening 9 converging toward the internally squared extremity of said member and terminating in a square opening 10.

11 is a conical member secured Within opening 9 by a nut 12 and having --a ball member 13 connected therewith by a rod- Patented se t. a, 1912. c

like extension 14 of said member. Ball member 13 rests in a socket in the engaged extremity (if member 3. A clampingring 15 suitably locked within the opening 1n the engaged extremity of member 3 adords means of adjustment for ball member 13.

Having fully described my invention, what I claim is:

A universal joint consisting of one shaft section "terminating at one extremity in an enlarged shell provided with oppositelylocat/ed parallel longitudinal slots, with a conical aperture receding from said shell and terminating in an enlarged opening 10, a ball supporting member disposed wlthin said conical aperture, 9. ball made integral with the last named member and adjusting means at the other end of said member; a second shaft-section having a socket formed in one extremity to receive said ball, a clamping ring removably secured in said socket and bearing upon said ball, oppositely-disposed prongs made integral with said second shaft-sectionand disposed within the longitudinal slots of the other shaftsection and sliding blocks arranged on said prongs capable of oscillation in the plane of the said shaft sections. 7

In testimony that I claim the foregoing as my own I have hereto aflixed m signature in the presence of two subscribmg witnesses.
